You’re right about liberals not thinking too deeply. Most don’t. They never get past how they feel and what they wish things could be like. Those that do rapidly see how the liberal world view falls apart when it comes crashing into reality. Then the liberal does one of three things. One, they get angry and scared, stick their head in the sand, deny the reality, and blame us (non liberals). Two, they accept the reality and change their world view - becoming something other than a liberal (a great awakening). Three, they decide that power and control are more important than honesty, and use their new-found knowledge to manipulate other liberals. (the fascist option)
